Spray tool power supply system and method

Abstract

A system may include an electrostatic spray tool having a turbine generator configured to generate electrical power to electrostatically charge a spray. The spray tool also may include a controller configured to monitor the electrical power from the turbine generator and to instruct a gas supply to vary a gas flow to the turbine generator based on feedback received from one or more sensors.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and benefit of U.S. Provisional Patent Application No. 62 / 261,728, entitled “SPRAY TOOL POWER SUPPLY SYSTEM AND METHOD,” filed Dec. 1, 2015, which is herein incorporated by reference in its entirety.BACKGROUND[0002]The present disclosure relates generally to spray tools, and, more particularly, to electrostatic spray tools.[0003]Spray tools, such as electrostatic spray tools, may be used to spray a coating material onto a target object, such as an automotive vehicle. The electrostatics help to increase the transfer efficiency of the spray onto the target object. Unfortunately, the electricity used by the electrostatic spray tool may be delivered through a power cord, which limits mobility of the electrostatic spray tool and requires a local power source such as the power grid. Furthermore, any extra weight added onto spray tools reduces mobility and comfort in handling the spray tools, which can also cau...

AI Technical Summary

Benefits of technology

The patent text describes a system that includes an electrostatic spray tool with a turbine generator to create electrical power for charging the spray. The system also includes a controller to monitor and control the electrical power via a gas supply. Additionally, the text describes a spray tool support module that can support the spay tool and operate in different modes based on the needs of the user. The system also includes a powder spray tool that receives a fluid flow and a powder flow and outputs a powder spray. The turbine generator in this system generates electrical power from the fluid flow to power the spay tool.

Problems solved by technology

Unfortunately, the electricity used by the electrostatic spray tool may be delivered through a power cord, which limits mobility of the electrostatic spray tool and requires a local power source such as the power grid.

Furthermore, any extra weight added onto spray tools reduces mobility and comfort in handling the spray tools, which can also cause reduced quality in the spray coating.
